This invention relates to improvement in means for setting members of se arable fasteners, that is, fasteners whi comprise complementary members 'arran on strips 6 of flexible material and adap to be interlocked. The more customary way of applying these fastener members is to place them, one at a time, on a strip, and b means of a press crowd the gripping ges to- 1o gether, but this'is a slow prom, and the In carrying out our invention we employ two holdingzplates 10 and 11. ese ates are'connecte by means of couplers 12 and 13 the lower p ate 11 being rigidlysecured to the couplers 12 and 13, and the upper late 10- is provided with studs 14 to enter oles 15 formed for them in the couplers 12 and 13, but it is obvious that these p ates might be otherwise connected together so that one ma turn with relation to the other, The a aeert faces of these plates are formed with a series of grooves. 16 and 17 to receive fastener-members 18, which ma be of any approved construction, but whic have gripping-jaws 19 and 20. The lower plate 11 1s located in a ve 21 formed in a dieblock. 22, which is located on the die-bed 23 of a press in line with the usual ra1 n' 24, but it is obvious, without illustration, that the late 11 mi ht be secured in an 'de-- gr P 8 y manner directly to the die-bed 23. Se-

-or comb 27. A spring 34 is oea Fig.2 is a broken side view of the same; p

'larly spaced. As many together and, as herein own,

cured to the ram to move therewith is a bracket 25, and pivotally connected with'the bracket is a yoke 26 .carryin a lon pusher ted tween the oke and bracket. The pivot 28 on who the yoke is mounted extends through a slot 29 m the bracket, so that it has a certain amount of rocking movement,- independent of the bracket, and mounted in the bracket and bearing u n the pivot 28 is a s ring 30 tensioned; y a screw-plug 31.

top-pins 32 are mounted in the bracket tolimit the swinging movement of the yoke. separable fasteners 18 are placed between the plates and the plates then located beneath the ram and a strip of fabric 33, to which the fasteners are to be applied, is laced beneath the comb 27. As the ram escends, the comb moves toward the plates '10 and 11 and forces the strip 33 between the 'aws 19 and 20 of the fasteners. Then, as't e ram continues its downward movement, it strikes the-plate 10 and rocks it so that the forward edge comes down and resses the jaws into eng%ement with the edge of the fabric-strip. y providing the spring 30 and the slots 29, the yoke 26 will yield against the tension of the spring 30.

and thus not interfere with the final downward movement of the ram.

- With this mechanism, all ofthe fasteners for a sm le strip are a plied at one move! ment of t e ram, and t e fastener'members are attached to the fabric-strip and reguairs of plates 10 and 11 as may be required can be used, and these plates filled with fastener members and passed to the operator-of the press.

We claim:

1. Means for setting membersof separable fasteners, consisting ;of two plates, one hinged with relation to the other, the adjacent faces of the plates formed with fastener-receiving grooves, a ram adapted to force the plates together, and means moved by the ram for inserting a stri of fabric between the gripping-jaws of t e fastener members. I

2. Means for setting members of separable fasteners, comprising two plates, one arranged above the other and one movable with relation to the other, the adjacent faces of said plates formed with fastener-member ooves, a ram ada ted to force the two plates together, a yo e moved by said ram,

and a comb mounted on said yoke, whereby a strip of fabric is inserted between the plates in advance of the closing movement thereof.

3. Means for setting members of separable fasteners comprising two plates, one arranged above the other and one movable with relation to the other, the adjacent faces of said plates formed with fastener-member reeves, a ram adapted to force the two plates together, brackets connected with said rain, a yoke mounted in said brackets, and a comb carried by said yoke, whereby a strip o;l' fabric is inserted between the plates in.

155 advance of the closing movement thereof.

lll'eans for setting members of separable fasteners, comprising two plates, one arranged above the other and one movable with relation to the other, the adjacent faces of said plates formed with fastener-member grooves, a ram adapted to force the two plates together, brackets connected with said rain, a yoke yieldingly mounted in said brackets, and a comb carried by said yoke, whereby a strip of fabric is inserted between the plates in advance of the closing movement thereof.

In testimony whereof, we have signed this specification.
